FAQs

Is the Frigidaire WF3CB the same as the WF2CB PureSource 2 water filter?

No. The WF3CB and WF2CB are separate part numbers with different housing designs and different installation types. The WF3CB uses a twist-in design while the WF2CB uses a push-button eject design. They are not interchangeable under any circumstances.

Is the WF3CB the same as 242069601 or 3762897?

Yes. 242069601 and 3762897 are alternative part numbers that refer to the same WF3CB PureSource 3 filter format. If your refrigerator currently shows either of those codes on the existing filter label, the WF3CB is the correct replacement to order.

Is the WF3CB the same as the ULTRAWF or FPPWFU01 water filter?

No. The WF3CB, ULTRAWF, and FPPWFU01 are separate part numbers with different housing designs built for different Frigidaire refrigerator model configurations. Despite all using twist-in designs, housing tolerances differ between each code and cross-code substitution is not reliable. Always order by part number.

Does the Frigidaire WF3CB filter water going to the ice maker as well as the dispenser?

On most compatible Frigidaire refrigerator models the WF3CB serves both the water dispenser and the ice maker from a single filter housing. Confirm this against your specific model in the Frigidaire user guide before ordering.

How do I reset the filter indicator light after replacing the WF3CB?

The reset procedure varies by Frigidaire model but typically involves holding the filter reset button on the control panel for three to five seconds after installation. Consult the user guide for your specific Frigidaire refrigerator model for the exact reset procedure.

Can I use an aftermarket filter instead of the Frigidaire WF3CB?

Aftermarket filters may physically fit the housing but certification levels and contaminant reduction performance vary widely between manufacturers. Using a filter that does not carry NSF 42 and 53 certification means contaminant reduction claims are unverified. For consistent tested performance use a certified replacement rated for the WF3CB housing.
